3-ingredient DIY sidewalk chalk in two easy steps!

All of my kids love playing with sidewalk chalk, so I decided to try making our own DIY sidewalk chalk and it was so easy! Plus, it only requires three ingredients. This is the perfect craft for any kid. Take a look!

Honestly, had I known that making sidewalk chalk was so easy, I would have done it a long time ago. Plus, it’s a super fun craft to beat summertime boredom and encourage creativity and hands-on learning. Here’s everything you need to make your own chalk right now.

Gather your DIY sidewalk chalk supplies

This recipe only requires three ingredients! And with the help of a few other supplies, you’ll have your homemade chalk in no time. Here’s a list of everything you’ll need:

Plaster of paris
Mica powder – you can buy this online or at a craft store
Water
Molds – you can use Jello jiggler molds, candle molds, silicone baking molds or even silicone ice cube trays.
Disposable paper bowls and spoons
Mixing bowl

#1: Mix together ingredients

Mix two cups of Plaster of Paris with 1 2/3 cups of water in a mixing bowl. Then, slowly mix in about one tablespoon of mica powder. Stir until completely incorporated. It should be slightly watery. Make sure you scrape the bottom of the bowl as you mix.

If you want mutiple colors of chalk, separate the mixture into disposable containers before adding the mica powder.

#2: Pour mixture into molds

Lastly, pour the various colored mixtures into your molds. You can use whatever kind of mold you want. I even used Jello jiggler molds and they worked great. Silicone molds work great but if you don’t have that, you can even cover the end of a toliet paper roll and fill that with the mixture. Just make sure you work quickly because this Plaster of Paris is designed to harden within 20-30 minutes.

Remove chalk from molds

Your chalk should harden within an hour or so, but we waited a few hours just to be safe. It was super easy to take the chalk out of the silicon molds. However, it took a little bit more finessing with the firm plastic mold, but we got those out okay as well.

That’s it! Isn’t that super easy? I couldn’t believe how simple and fun this DIY sidewalk chalk craft was. Even my older boys had fun making them. I hope it’s just as fun for your. Let me know how it goes in the comments below.
